Development of a questionnaire to measure attraction toward sweet, salty, and fatty foods in children

Childhood obesity may be responsible for a major alteration of life quality in children and in future adults. The causes of obesity are multiple and obesity results from a chronic imbalance between food intake and energy expenditure. The challenge is to understand the cause of this imbalance. In this context, this study aimed at evaluating the contribution of the attraction toward salty, sweet and fatty foods. Thus, the first aim of this study was to establish a tool to assess children’s attraction toward sweet, salty and fatty foods that could be used later in large-scale cohorts. The second objective was to compare this questionnaire to sensory tests measuring the overall liking for sweet…

Aroma volatile metabolites at olfactory mucosa level evidenced by in vitro PTR-Tof-MS studies

International audience; Olfactory mucosa can metabolize odorants through various enzymatic mechanisms participating in their clearance and therefore in the termination of the olfactory signal. Preliminary ex-vivo studies using headspace-GC revealed the formation of volatile metabolites when odorant molecules were injected above a fresh explant of rat olfactory mucosa. However, this method did not allow accessing the data during the first five minutes of contact between the odorant and the mucosa, thus limiting the olfactory biological significance. Using a direct-injection mass spectrometry technique (PTR-MS) we have been able for the first time to investigate the first moments of the enzym…
